In the latter case, the mobile communication company system 300 may include a predetermined system for tracking and collecting the position of the mobile terminal 200.

When the first verification information includes the time information of the digital image, the acquisition module 120 determines that the digital image is a digital image because the transmission time is very short when the digital image is transmitted through the network. The time transmitted to the validation system 100 can be regarded as the time when the digital image is received from the portable terminal 200. [

If the first verification information includes the identification information of the device that photographed the digital image, the identification information of the portable terminal may be transmitted to the portable terminal 200 or the mobile communication company system 300).

The verification module 140 may verify the validity of the digital image by comparing the first verification information and the second verification information.

More specifically, when the first verification information includes the location information of the place where the digital image is photographed, the verification module 140 determines whether the location of the location where the digital image was photographed, It is possible to judge whether or not the condition is satisfied.

The fact that two positions satisfy a predetermined position condition may mean that the two positions correspond to a predefined positional relationship. For example, if the distance between the position of the place where the digital image is photographed and the position of the portable terminal is within a predetermined limit distance, the verification module 140 determines the position of the place where the digital image is photographed, It can be determined that the position satisfies the positional condition.

If the first verification information includes the identification information of the device that photographed the digital image, the verification module 140 determines whether the identification information of the photographed device and the identification information of the portable terminal match the digital image Can be determined.

If the first verification information includes the time information of the digital image taken, the verification module 140 determines that the time when the digital image was photographed and the time when the digital image was received from the portable terminal is a predetermined time condition Is satisfied.

The satisfaction of a predetermined time condition between two times can mean that the two positions correspond to a predefined time relationship. For example, when the difference between the time at which the digital image is captured and the time at which the digital image is received from the portable terminal is within a predefined limit period, the verification module 140 determines that the digital image is captured, It can be determined that the time when the digital image was received from the terminal satisfies the time condition.

When the position of the place where the digital image is photographed and the position of the portable terminal satisfy a predetermined positional condition, the verification module 140 determines whether the digital image is the identification information of the photographed device and the identification information of the portable terminal And judges that the digital image is valid when the digital image is photographed and / or the time when the digital image is photographed and the time when the digital image is received from the portable terminal satisfies a predetermined time condition.

Meanwhile, the digital image may be any one of a facial image of the user of the portable terminal, an ID image, and a unique authentication object (IC card, OTP device, security card) captured by the portable terminal. In this case, Can be used for non-confidential self-certification.

Here, the unique authentication object may be an IC card, an OTP device, a security card, a credit card, or the like, which may be various objects or devices that can be used for authentication of the owner.
